This was a design by French designer Charles-François Galand (1832–1900). His original design was an open frame, double action revolver patented in 1868. It was manufactured in both 9mm and 12mm variations. The long extractor lever, serving as the trigger guard made it an easily recognisable design. It was also a period where the storm clouds were gathering over France and the North German Confederation, led by the Kingdom of Prussia. Hostilities broke out in July 1870 with the Franco-Prussian War. Afterwards Galand entered his design for the French trials but lost out to the Chamelot-Delvigne Mle. 1873. Galand then turned to the civilian market and launched his Tue-Tue hammerless revolver in 1892/93. The 8mm Tue-Tue is similar to the 8mm Non-Regulation revolver, which was a civilian model of the 8mm Lebel M92 that replaced the larger M73. (Erlmeier, Brandt Ref. 108).
